Abstract (en)
[origin: EP3609296A1] A power supply device (100) includes: an input unit (10) configured to receive an input voltage from outside; a power supply unit (20) configured to generate a power-supply voltage from the input voltage inputted through the input unit (10); an output unit (30) including an output terminal (32, 33) configured to output the power-supply voltage; and a lighting circuit (12) connected to the input unit (10) and configured to be turned on in response to application of the input voltage. The lighting circuit (12) is configured to vary in lighting mode depending on the input voltage.
